如何为对象创建行为主体并在另一个组件上订阅它?

问题描述

我已经在服务类中创建了一个行为主题.

I have created a behaviour subject in a service class.

    public personObject: BehaviorSubject<any> = new BehaviorSubject<any>({
                                               personId: 1,
                                               name: 'john doe'
                                               });

在导入此服务的组件上，我已订阅了以下行为主题:

On a component that imports this service, i have subscribed this behavior subject like this:

`        this._subscription.add(
            this._bankService.personObject.subscribe(data => {
                this.personObject = data;
                console.log(data);
            })
        );`

但是我无法获得有关行为主体的确切数据集.请帮忙.

But I am not able to get exact data set in behavior subject. Please help.

修改我忘了提到我使用ViewContainerRef来创建同级组件.因此，我添加了一个对我的问题的评论很少的答案.

EditI forgot to mention that i have used ViewContainerRef to create my sibling comnponent. So i have added a answer with few comments on my issue.

推荐答案

我忘了提到我正在使用ViewContainerRef创建同级组件，结果发现行为主体与使用创建的组件的工作方式不同ViewContainerRef.

I forgot to mention that I was using I was using ViewContainerRef to create a sibling component and it turns out behavior subject does not work the same way with component created using ViewContainerRef.

任何对象的其他明智行为主体的工作方式与数字或字符串完全相同.我现在使用@Input将数据发送到组件.

Other wise Behaviour subjects of any object work exactly like with number or string. I used @Input to send data to component for now.
